Application filed January 23, 1908. Serial No. 412,305.

To all wlwm it .may concern:

Be-1t known thatl, JAMES BUTLER, a citi-` zen ofthe United States, otthecity of St.

Catherines,` in thegcountyof Lincoln, in Vthe Province of Ontario,Canada, have invented certain newand useful lmproyements in Scrapers, ofwhich the followingis the speciinvention is to simplify and cheapen thecon- A catnzm.A

1 M invention relates to improvements ,1n revoving drag Scrapers andtheobject of the struction of that form of drag scraper which may beldumped, and restored to its operative position without the driver havingto exert -any appreciable force in dumping vas covered by my Patent-1No. 841929, granted January., 22, 1907, in the United States of America,and No, 100,514, granted August 21, 1906, in the Dominion of Canada andit" `consists essentially of a sc ra er body, two pinsV extending fromeach site thereof, one

pin extending centrally from each side, and

the vother pin extending from each side of the scra er in proximity tothe mouth thereof, a

han le having forked ends extending to each side of the scraper body andswung on the central pins,extending therefrom and the members of theVfork being provided with upturned ends, pi s extending inwardlydrom theextremity o such ends, angle pieces-havpins extend and jaw ends engagingnorma the pins inproximity to the mouth of the scraper, and providedwith pins on which the bail of the scraper is swung, a cross barextending between the members of the forked handle in proximity to thescraper body, an

engaging piece on the back of the scraper body, a pivoted spring latchpiece normally engaging therewith, and a pivoted catch piece ivotedtothe rear of the cross bar and extending over the same to engage withthe engaging piece on the back of the scraper body as hereinafter moreparticularly explained.

Figure 1 is a pers ective view of my scraper. Fig'. 2 is a side eevation partially broken away and inseetion to exhibit my construction.vFig. 3 is a similar view to Fig. 2 showing the scraper in position fordumping. Fig. 4 is a similar view to Figs. 2` and 3 showing the scraperin the dumped position. Figs. .5, 6, and 7 .are detail views of thelower end of the forked handle and the engaging angle piece in thenormal, dumping and dumped Specification of Letters Patent.

positions. Fig. S is ,a plan detail' ofv lthe with an engaging piece Af'secured to the' back thereof'.

B is the scraper handle which'branches oit into two' members B and B2extending to each side of the scraper body and swung on` the pins A@ B3is an upti rned portion extending at right angles form the end of theforked 4members of the handle.

B4 is a pin extending inwardly from the portion B3.

B5 is a cross bar extending between the forked members 'of the handle inclose proximity to the back of the scraper'body.

B6 is'a looped piece (see Fig. 8) extending rearwardly from the crossbar B5.

'B7 is a catclrpivoted on the pin B8 and designed to be normally held inengagement with the' piece A3 by means of the spring B9. B10 is a chainsecured to the piece B7 elow. the pivot pin B8.

B is a grip lever to which the chain B10 is attached and whereby thecatch B7 is released;

B12 is an engaging piece swung on the pin B8 and designed to engage withthe piece A3 to dump the scraper.

D is an angle piece. having a slotD (see Fig. 5) through which the pin Aextends. The pin BL1 normally engages the up er end of the member D2 asshown particu arly in Fig. 5. The angle piece D is provided with an endjanv D3 normally engaging with the in A2 and a pin D4 on which is swungthe bail C of the scraper.

Having described the principal partsl'involved in my invention vI sha1briefly de'- To dump the scraper Ipress on the lever'. B'11 so as torelieve the catch B7 fronr the' engaging piece A3 and depress the handleB into the dotted position shown in Fig.` 2. By this movement of thehandle B the piece B12 is brought into engagement with the ieee A"x onthe sera er and is enabled to ass P P P beneath-'the same by swinging upon its 'pivot B8. dihenv the handle Bis su'iciently depressed the pieceBP drops beneath the piece A3`so as to engage with the underside uponthe handle 'B being rlaised. By the same operation of the handle B thepin Bt'engaging with the member D2. of the an le-piece D carries suchangle piece rearwardy position shown in Iig. 6 and awayfrom the in 2. pThe' scraper is now free to turn; The operator raises slightly on thehandles B so as,l

to give the edge of thescrapera purchase on the ground. The"point ofdraft' is .moved thereby from the pinA2 to the pin A and the.'

scraper is turned easily tjo dump and. into the position shown in Fig.4. l/Vhe'n inthis position the parts are so arranged 'that the catch-B7, engages the edge of the scraper. By lifting on the handle B` thescraper may be easily restored to its norinal position..

From this description it will be seen that I have devised a very simplearrangement and; one Wlnelrwlll not be iable to get out of order.

What I claim as my invention is: 1.-V In a scraper of the class.described7 the y into 'the engagement piece secured-to the bac-k oflthe .scraper body, oi across bar extending-be# tweenthe members of thehandle anda' catch piece pivoted to the back'of thebar and 'eX- tendingover the same andl engaging v'with the .engagement piece as and for.thevjpurpose' specified.

2. In a' Semper of the ,dass awaited, ai@

combination With the scrape-r` body, :the

forlged handle pivotedrto each Vsideof the body and an engagementpieeesecured to the back of the scraper body, of a cross bar exftendingbetween the nieinbers of thehandle,

of' Vthe cross-bar, a catch pivotedtherein, a

spiral spring connecting* theqcatch above its' purpose specified.
